The objects of this invention are to provide a light weight, economical, efficient, small car,

which can be readily handled in crowded city streets, particularly adapted for parcel delivcry purpose and which can be produced at reasonable cost from standard automotive units.

Further objects-of the invention and the novel features of construction, combinations and relations of parts by which such objects are attained are set forth in the following specification.

The drawings accompanying and forming a part of the specification lllustrate one prac- -7 tical commercial embodiment of the invention, but it should'be understoodthat the structure maybe modified as regards this 1 particular disclosure without departure from.

the true spirit and broad scope of. the invention.

I Fig. 1 is a side elevationillustrating the invention embodied in the form of alight parcel delivery car and indicating in particular how the fore part of a motorcycle is utilized v as the power plant of the vehicle, combined with a standard rear axle and differential unit; Fig. 2 is a top plan view of the rearward portion of the vehicle illustrating particularly the attachment and mounting of the rear v n1otorcycle forks on the rear frame andthe drive gearing to the rear axle;;F1g-. 3 1s a.

Fig. 6 is a similar view as on line 6 6 of Fig. 2.

tion, a motor cycle, complete except for the rear wheel is used, the same being indicated at 7 as of a typical commercial design. The:

removal of the rear wheel leaves the rear a frame indicated generally at 8 and connected by springs 9 with a standard rear axle unit 16 containing a diflerential at 11 and mounted on rear wheels 12.

The power plant of. the motorcycle at 13 In the illustratedembodiment ofthe inven forks of the machine freeto be coupled with has a chain drive 14 for the gearset of the n machine at-15 and the drive for the rear axle is taken off from this gears'et by a chain 16 substituted inplace of the chain previously the gear box 17 and carryinga bevel gear 21 in mesh with a bevel pinion 22 on the forward end of shaft 23, which is coupled through the universal with a shaft 24, the latter carrying the difierential pinion 24a in meshwith the.

ring gear of the differential. This shaft 24 may be a shortened length of the'propeller f shaft which comes with the realraxle assembly. I I

As shownin Fig. 2, the universal joint is locatedsubstantially in line with the pivoted front ends 25 of the rearfaxle springs and as appears in this viewv and in Fig. 5, the

front section of the 'sha-fting is journalled in a casing 26 rigidly connected with or 3 forming an extension of the gear box 17,

"while the rearward section ofthe shafting 1 is journalled in a casing 27 rigidly connected with or forming an extension of the difi'erential housing, said two shaft casings having a as universal connection at 28. The body of the gearbox 17 may be a duplicate of the dif:

ferential housing, as indicated in 2 except for the fact that it is closed at opposite sides by special. end plates 17 a and 17 b carry-Leo ing the bearings for the bevel gear shaft 20. The bevel gear 21 and pinion 22 may be duplicates of the ring gear and pinion of the differential. Theuse of these standard readily available parts is desirable from-the '95 standpoints of cost and repairs. The rear shaft section'24 is shown as having a splined connection'at 29 with the rear member of the universal joint to allow for variations indistance between centers. For adjustment pur-'-100 V 37- in .thebridge. box is shown-supported'by' a saddle or cradle T 38 adjustably fgear box 38a of-the motorcycle'stru'cture at E2220 poses, the rear shaft casing 27 it shown as having a telescopic mounting in the sleeve projection 30 of the differential housing, the latter being split at its forward end at 31 and secured in the adjusted relation over the shaft casing by the split clamp 32.

The gear b02017- is shown as. rigidly-atpiece 33 shown held to the rear frame bars 34 of the motorcycle by U-clamps 35 and for and aft adjustment of this gear unit relative to the gearset of the machine is provided for in the illustration by having the bolts'36 which suspend the gear box from the bridge piece operate through longitudinally disposed slots At the bottom, the gear bolted to the-underside of the 39, Figure 2.

This long bolt is indicated in"F=ig.

-.tendingfuplfrom"the sides of the frameon forwardly and inwardly inclined slants-and secured at their upper ends to bllG/IllObOfcycle frame asby' means of the split-clamp construction illustrated at 49 in Figs. 1 and3.

The brakes of the rear wheel'assemblyare "utilized in the i-llu'strationby coupling brake shaft extensions" '50 to the brake shafts :51,

- which form part of the rear axle assembly as by means of the rivetedcouplings or-collars 52- and by mounting the brake rocker arms 53 removed from said brake shafts on 3 these shaftentensions at oppesite sides of the diiferentialhOusiIIg, "where the inner ends of said'shaft'extensions are shown jour-- nailed in special bracketsw54; bolted onto the sides of the housing. These brake operating-arms "53 'areshown inFigs. 3 and 4"as pivotally connected at their lower'ends' byan 4 equalizer bar 55 to which is attached a brake rodfih connected bylinkage'57, Fig.1, with the brake 'pedal'58' of the motorcycle.

This construction serves to further brace and connect the two main frame portions of the 30 Thebol-ts 41, Figs. 2-and3, rigidly secure the rear forks of the-motorcycle frame to the rear axle frame. This leaves the chain adj ustto be u-tilized for-adjusting the chain drive 16. Such mechanism is shown as bolts 62 -'mounted: on" the forks in position to operate against'the bolts-63 positioned in the slots 64of the forksand extending through correspon'dingislots 652in the attaching lugs42,

The invention-it-will be seen, makes it'p'ossible to construct, at comparatively low cost and largely' froin readily obtainable standard 'automotive parts, a light but rugged and dura'ble ear especially suited fordelivery pur- "poses'i-n crowded city streets.
